\chapter{Experiment Results}
This chapter contains detailed analysis of some of the experiments performed
for implemented ARQ and J-ARQ protocols.
\section{Modem Simulator}
\subsubsection{ARQ Protocol}

\caption{ARQ}
\end{figure}

Transmission completed with ACK in: 16583(msec)
propagation delay = 477(msec)

\subsubsection{J-ARQ Protocol}

propagation delay = 477(msec)
Transmission completed with ACK in: 26156(msec)

\section{Field Trials}
\subsubsection{Variable Block ARQ (ARL water-tank)}
  \begin{figure}[h!]

\label{250bytearqtank}
\end{figure}
Figure \ref{250bytearqtank} represents the timing diagram for transmission and
reception. Here after reception of ACK for first block, transmitter modifies the
block size to the remaining number of packets.
\begin{itemize}
  \item Data size = 250 bytes
  \item Transmission completed with ACK in: 13645(msec)
 \end{itemize}

 
 \subsubsection{Fixed Block ARQ (ARL water-tank)}
  
\begin{itemize}
  \item Data size = 250 bytes
  \item Transmission completed with ACK in:
 \end{itemize}
 
 \subsubsection{J-ARQ and J-ARQ with rateless codes (Pandan Reservoir)}
 J-ARQ field testing requires minimum propagation delay which cannot be obtained
 in ARL water tank so tests needs to be performed in Pandan Resevoir. Currently
 testing is in progress. The report will be updated after completion of all
 required tests.
